WASHING-MACHINE.

Application led December 27, 1918. Serial No. 268,508.

To ZZ whom t may concern:

Be it known that I, JOSEPH H. BAIE, a

citizen of the United States, and residing o ying-Machines, of which thefollowing is a specification.

This invention relates to laundry machinery and more particularly to theclass known as washing machines, of the power driven typeand adapted todo washing on a com; mercial scale.

TheJ primary object of the invention is to afford a mechanism whichcombines in one simple organization means for performing severaloperations at a time on'the mass of wash placed therein to be washed.These operations are, squeezing, rubbing, injecting water and air,swishing, separating and turning, aerating and suctioning.

`Another object of the invention is to provide means for easily and'quickly changing the water, and also for loading and -unloading themachine with facility.

To this end, I provide the mechanism set forth in the accompanyingdrawings and description thereof.V In th'e drawings:

Figure 1, is a side view `of the machine shown in operative relation.

Fig. 2, is a front view showing both outer and inner tubs tilted so asto admit of easy loading and unloading. f

Fig. 3, is an enlarged detail ofone of the gryatory agitators, and itstank in which a piston'is fitted.

Fig. 4, is Ya detail of the mechanism by which the pulleys are reversedat the end of Fig.'5, is a detail of the bottom of an agitator showingthe suction pipes, and

Fig. 6, shows in perspective the shifting mechanism shown in Fig. 4.

The oper-ation of the machine is fol*` lows: A large tub 1, forming ahalf cylinder, is pivotally mounted on a housing fr-ame 3.

This tub is normally held in a horizontaly position, but may be up-tilted by means of a handle 22 having a mion 20 thereon in gear with arack 21 on t e tub. Inside and conforming to it and being pivoted incommon with it is another tub 2. These tubs are preferably constructedin the conventional way, having proper end frame work 44, with radiallydisposed braces 19 and planks 24 bolted to the frame by means of screwsor rivets 23. The ends may be of wood or copper plates.

At the pivotal or axial point is a crosscrank shaft 11 having fastthereon at the respective sides pinions 11 and, 14. These pinions 11 and1 4 are respectively in mesh with gears 9 and 9, which have smallpinions 37 and 26 axially fast thereto -and in mesh with internal racks12 and 12 'on the inner tub 2. The intermediate gears 9 and 9 and theirrespective pinions 37 and 26 are supported and havetheir bearing in anupward vextension 13 from the main frame 3. The inner tub 2 hasperforations 38'so that the water in the outer and inner tubs may freelycommunicate.. The crank-shaft 11 has two or m-ore agitators 4 thereon,connected with it by means of a bearing 36 on the end of an arm 47,pivoted at 48. The two parts-of the bearing box are held together bymeans of bolts 37. There are two tension springs 35 and y35 which holdthe bearing 36 in about the same position in re- 'lation to the agitator4, except when it is borne down on a thick mass of wash the springsallow it to yield the required amount to allow the crank 11 to rotate.The agitator 4 has at its bottom where it impacts on the wash a numberof openspouts 8 projecting from the cross pipe 7 associated with acommon pipe 6, whichrcommunicates with the piston 29. This piston isfitted in a bucket cylinder 5 which is pivotally suspended at 27 by aframe 29 held by bolts 51. The pipe 6 communicates with the bucket 5 bymeans of holes 30. As the shaft 11 revolves the agi- Specification ofLetters Patent. Patented Aug, 24, 1920.

tator 4 performsa gyratory movement,'mov

5. As it moves down the water in the bucket is forced out through holes30 down the pipes 6 and 7 andfrom the nozzle 8, forcing the ejectedwater and air through the water and through the clothes, filling thewater and clothes with bubbles which loosen the dirt equivalent toboiling. As the agitator 4 is tilted, piston 29 rises in the cylinder 5sucking water and air, forming a suction on the spouts 8 which tend toadhere the clothes thereto. This carries the top ones up and forwarduntil the end of the lift, when they are dropped and repelled by thegush of water from the nozzles 8 caused by the piston 29 moving down. Asthe agitators work in alternate relation to each other, it is preferableto have a partition between the respective agitators in tub 2.

As the operation proceeds the down end` of the inner tub gradually risesand the wash is gradually moved toward the rising end,

and the tendency is always to turn the inside` wash outward. At the endof the up tilt of the inner tub, the belts are shifted and the operationis reversed. This takes place automatically in the following manner:

On the power end of shaft 11 are three pulleys 46, the middle of whichis loose, and

V15. guard loops through which the drive belts pass. These guards are onadjacent pulleys so that one of the belts i on the loose pulley v andthe other on a fa t one. One belt is straight and the other with a halftwist. On

-bearing shaft 53 is mountedl a shift mecha nism 42, having below aprojection 43 in contact with stiff spring 52. Projecting upward arethreearms. The first, 42 has a curved angular sector 40 resting' in theslot 39 of the sliding shift piece 36. The latter two 17-17 extendupward also'and'have the free ends 18-18 turned in into the path of thetub 2. As the tub 2 up tilts at the 18 end it abuts against 18 andcarries arm 17 with it until lug 4'3 has been dragged over the hump ofshifting spring 52, when arm' 17 drops away from its contact with the upend of the tub and member 17 with its turned in end 18 drops against thedown end side rim. The sector 40, resting in slot 39 of the slide 36shoots through said slot and by means of the incline 404 thereon, shifts36 and the belts controlled thereby.

The agitator 4 is coveredwith a plate cor- 40 rugated and indented at 31to meet the requirements and fastened to the pipe 6 and supporting it bymeans of bolts 32, 33 and 50. The machine may be anchored to the fioorby means of bolts 45. The outer tub f 46 1 has connections 49 at eitherside by means of which hose may be attached, the one by means'of whichto put in water and the n lother to withdraw it. Water way be added andwithdrawn while the washing operation 60 proceeds.

struction described may be resorted to without affecting the spirit ofthe invention.
